How I can help

One engineer. Full product perspective.

Explore all services ↗
01 / BUILD↗

Front-end & full-stack development

Angular web and React Native mobile interfaces, robust .NET services, useful APIs, and databases designed for real workloads.

02 / IMPROVE↗

Architecture & performance

Clear technical direction, better data flows, faster SQL, and practical fixes for systems that have become hard to change.

03 / ENABLE↗

AI delegation & orchestration

Help developers lead AI employees, delegate classical tasks, and keep the knowledge needed to own their output.

Experience in the real world

From customer screens to factory-floor timing.

I work across the stack and stay focused on the business problem behind the code.

Real-time systems

Software working in step with warehouse robots.

Business logic, WMS integrations, robot communication, Tier 2 support, and SQL performance where delays mattered.

C#SQL ServerWMSReal time
Maritime security

Web products protecting computers at sea.

Full-stack work in an R&D team building cyber-protection software for maritime crews and remote environments.

Angular.NETAPIsDocker
Team multiplier

Better teams share what they know.

I push internal training so expertise never lives in one head. I also help developers lead AI employees, delegate work, and stay ready as the boundary of delegable work keeps moving.

How I work ↗

Senior enough to see the system. Hands-on enough to ship it.

I value broad technical perspective, direct communication, and ownership. I am always open to useful conversations about software, AI orchestration, and helping developers grow.
